People can be mean, and Jimmy Kimmel knows it (remember the time Kanye West angrily ranted at him?). And on Jimmy Kimmel Live Thursday night, viewers were treated to the sixth edition of his "Mean Tweets" segment, in which celebrities read rude, offensive tweets about themselves.

"From time to time, we like to shine a light on those who post cruel and horrible comments on Twitter. People can be vicious, and it hurts," Kimmel explained. "So to raise awareness and to maybe make people think twice before they post something awful, once again we've assembled a group of famous faces, including some of our guests tonight, for this, our sixth edition of 'Mean Tweets.'"

Some of the best (read: ones that are repost-able on this family-friendly site) burns:

"I'm just gonna throw this out there. I hate Jon Hamm. I hate his face. I hate his pig name. I hate how smug he always looks. I hate Jon Hamm," reads a fully bearded Jon Hamm, to which he gives the camera the sad frown of a man who just read a mean tweet about himself.

"The Bob Balaban storyline on Seinfeld is creepy as (expletive). My stomach turns when I see that goofy little worm," Balaban reads. "Hah! That's really good," he remarks.

"Whatever. Tom Hanks is a whiner. Oh boo hoo, so you have a tropical island all to yourself. (Expletive). You. I have a turtle sandbox, (expletive)," Hanks reads, really emphasizing that last word.
